' in such a manner that after the forms have beenremoved portions'ofthe hanger are ex- '10 posed'permitting the same to be bent into a suspended position ready to receive and support ceiling supporting bars or the like in a convenient position ready to have expanded ceiling laths secured thereto.

It is an object of this invention'to provide an improved method for hanging ceilings by o means of brackets adapted to be partially 1mbedded in concrete ceiling beams with flanged apertured portions of said brackets exposed "29 to permit the sameito be bent downwardly to form supports .for receiving ceiling bars.

It is also an object of this invention to prof vide an improved ceiling hanger constructed of sheet metal or other suitable material emi253 bracing a toothed or irregular supporting plate-having, formed thereon, an apertured angle plateadapted to be bent into the plane of the supportingplate after the hanger has been mounted in place.-

' 0 It is a further obje'ctof this invention to provide a ceiling hanger adapted to be seated within a ceiling beam form and partially imbeddedin concrete in such a manner that a portion of the hanger may be bent into a position to support a ceiling carrying bar to of the hanger may be bent into substantially a vertical position permitting a ceiling supportingbar to be supported on said hanger.

this invention will be apparent from the dis-- closures in the specification and the accompanying drawings.

- This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 4: is a fragmentary sectional perspective view of the concrete floor or ceiling with the form members removed and the portions of the hangers bent to afford a convenient support for ceiling bars.

Figure 5 is an enlarged fragmentary detail section taken on line VV of Figure 4; illustrating the normal position of the lower portion of a hanger in dotted lines and the supporting position of the hanger in full lines.

Figure 6 is an enlarged fragmentary transverse'section of a ceiling beam illustrating a modified form of positioning a ceiling hanger in place and means for tying a ceiling bar in position seated on the supporting flange of the hanger.

As shown on the drawings:

The improved ceiling hanger is preferably constructed of galvanized annealed sheet metal of any desired gauge and is of unitary construction adapted to be stamped from a sheet of metal and then bent into position forv mounting. The improved hanger'comprises a supporting plate 1, the side or longitudinal edges of which are provided with a plurality of notches 2 forming an irregular or'toothed margin on each side of said supporting plate whereby the concretemay lodge or seat in the notches or recesses 2 when the hanger is mounted in place. 'lntegrally formed at sub stantially right angles to the lower edge of the supporting plate 1 is an intermediate or bar receivingportion3 having an opening or aperture 4 therein with one end thereof extending to the upper edge of a flange 5 integrally formed at substantially right angles on the outer edge of the intermediate hanger portion 3.

Theimproved ceiling hanger is adapted for use in an improved method for hanging or supporting ceilings from'concrete floor and ceiling structures or thelike. In a building construction when it is desired to construct a concrete floor from whicha ceiling is to;

be hung a plurality of form beams 6 are first mounted in position upon any desired kind of supports and have supported transversely across the upper edges thereof a plurality of parallel beam form boards 7 upon which beamform metal pans or shells 8 are supported forming a plurality of. parallel pockets or beam troughs. After the form mem bers 7 and 8 havebeen mounted in proper relatlonupon the supporting framework or beams 6 the improved ceiling-hangers may be set in spacedpositions longitudinally Withineach of the beam troughs and upon the 'baseboards 7 forming part of the beam forms.

To -mount a ceiling hanger in place a slot 9 V (FigureB) is cut longitudinally in the up- .per face of thelbeam form board 7 to receive the hanger flange 5 seated therein with the intermediate plate 3 of the hanger seated flatly upon'the upper face of the board 7, thus holding the hangersupporting plate 1 in substantially a vertical position projecting upwardly into-the beam forming space provided above a form board 7 and between a pair of the metal shells 8. The improved ceiling hangers may thus beset in position at spaced intervals longitudinally along the beam form board 7. As illustrated inv Figure 2 the hangers are placed on alternate form boards 7.'1;The spacing arrangement of theceiling hangers, however, is left to the contractor in charge of the job. After the hangerhas been seated in place within a beam form concrete is poured over the form members- 7 and 8 to form a concrete floor section 10' and a plurality ofconcrete ceiling beams 11 which may be reinforced if desired. 'It will thus be noted that with the concrete board in place the notched or toothed supporting plate 1' of a hanger is completely imbedded in the concrete with the concrete fillingthe notches 2 to rigidly hold a hanger'in place,

thereby obviating any danger of pulling the hanger out of. the concrete beam after the concrete has properly set. After mounting a ceiling hanger in place, as described, and

imbedding the same in concrete, the support ingbeams 6 are removed after which the beam form planks or boards 7 and the metal forms 8 are pulled off leaving the'flanged plates 8 of the'ceiling hangers exposed, as

shown in dotted lines in Figure 5. The exposed plate 3 of each of the hangers is now released by any suitablemeans by engaging any suitable toolbetween the hanger plate 3 and the bottom face of a concrete beam. The plate 3 is then bent from the dotted line position ofFigure 5 into the plane ofthe hanger supporting plate 1, thereby positioning the flange 5 in a substantially horizontal position parallel to the bottom face of the concrete beam in alignment with other ceiling hangers supported in adjacent or alternate ceiling as illustratedin Figure 5 metalchannel ceiling supporting beams or bars 12 are projected th-rough thehanger openings 4: withthe lower flanges of the channel beams resting on the flanges 50f thehangers. The ceiling supporting arms or bars may thus be readily secured in place ready to'have ceiling laths1 beams. 'With the ceiling hangers arranged tied or otherwise secured theretoito receive the plaster to'form'the ceiling. H

Ifdesiredthe improved ceiling hangers may be mounted with thesupporting plates 1 of the hangers mounted transversely inthe beam forms, as illustratedvin Figure '6, in which event the flanges 5 0f the hangers would be seated in transverseg'slots cut in the,

upper faces of the beam form boards 7.

After the concrete has been poured in the forms the forms may be removed and the hanger plates 3 bent downwardly intothe planes of the supporting plate 1 and-ceiling supportingchannel' bars 12 may then be seated upon the hanger flanges 5 andstrapped thereto by means of retaining wires or straps 13. It willbe noted that the improvedceiling hangers maybe mounted imposition to permit the ceiling supporting channel bars to be either projected through the apertured plates 3 a nd seated on the flanges 5 or may be placed parallel to the hanger plates 3 resting upon the flanges. 5 and secured thereto by f any suitabletype of retaining means.

1 While an: improved ceiling hanger has been described constructed of'sheet metal bent into a desired form, it will, of course, be

understoodthat a hanger may beconstructed of wire or other suitable materials and may I be mounted in place similar to the arrangement described in connection with. the illus trated hanger.

I am aware that'many details of constructionmay furthermore be varied through a V tending in a direction Opposite to said sup- .3. A unitary ceiling hanger porting plate, said intermediate plate adapted to be bent into the plane of the supporting plate after the hanger has been mounted in place for use.

2. A ceiling hanger arranged to be embed- (led in concrete comprising a notched supporting member, a plate integrally formed at an angle thereon having an opening therea plurality of notches in the'longitudinal' margins of the opposite end thereof.

4. .A ceiling hanger formed from a single sheet of metal, bent into substantially Z shape with the ends in substantially parallel planes and an intermediate portion substantially perpendicular thereto, and With one of the ends shorter than the other, said intermediate portion having an aperture therein ad- .jacent and terminating at the shorter end portion. I

5. A ceiling hanger formed from a single 7 sheet of metal, bent into substantially Z i shape Withthe ends in substantially parallel I planes and an intermediate portion substantially perpendicular thereto, and with one of the ends shorter than the other, said intermediate portion having an aperture therein adjacent and terminating at the shorter end portion, said intermediate portion being bent into the plane of thelonger end after the same has been secured in place for use and with the shorter end then lying in a plane perpendicular to the longer end for supporting aceiling bar.

6. A ceiling hangerformed from a single sheet of metal, bent into substantially Z shape With the endsin substantiallyparallel planes and an intermediate portion substantially perpendicular thereto, and With one of the ends shorter than the other, said intermediate portion having an aperture therein adjacent and terminating at the shorter end portion, said intermediate portion being bent into the plane of the longer end after the same has been secured in place for use with the shorter end then lying in a plane perpendicular to the longer end for supporting a I ceiling bar, said apertured intermediate portion arranged to receiveand support a ceiling bar.

7 Aceiling hanger comprising a plate of sheet metal bent to provide a supporting pon tion, an intermediate portion substantially perpendicular to the supporting portion, and

a flange portion at the other end of said intermediate portion, said flange and said supporting portion being in parallel planes and extending in opposite directions from said intermediate portion, said intermediate portion having an aperture therein for the re- I I I a l ception of a ceiling bar When said hanger 1s supported in place for use and said intermediate portion is bent into the plane of said supporting portion.

In testimony whereof I have hereunto subscribed my name.
